To all whom it may concern:

Be it known that I, LOUIS J. BRUNE, a citizen of the United States, residing at ,Algiers, in the parish of Orleans, State of Louisiana, have invented certain new and useful Improvements in Railway-GainToilet Locks; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in toilets and particularly to toilets used on railway cars One object is to provide a novel and simple means for closing the receptacle or tank of the toilet bowl so as to prevent the matter from dropping on the tracks in depots or at wa stations.

' other object is to provide means actuated by the application ofthe air brakes of the train which will close the receptacle,

when the train stops, and which will open the receptacle when the train is again in motion and the brakes ofi. Other objects and advantages will be ap- QI pa'rent' from the following description when taken in connection with the accompanying drawing.

The gure 1s an enlarged view of the invention, 1n section, shown in connectlon wlth I the parts of the brake system of the car.

. Referring particularly to the accompany- ,ing drawing 10 represents the floor of the railway car, 11 the bowl of the toilet, 12 the flush tank, and 13 the receptacle disposed belowth'e car and connected to the bowl by the pipe '13. The car is provided with the usual. air reservoir 14 which supplies air to the brake cylinders of the car, the brake cylinder 29, the triple valve 30, and the conductors valve 81. At one end of the recep tacle there is mounted a pivoted door 16 which is to, be closed when the train is ina depot or at a station so that the refuse from the toilet which enters the receptacle will not be discharged on the tracks. Mounted on the bottom of the car above the receptacle is a cylinder 17 in which is arranged a piston 18 carrying a piston rod 19 which extends through the rear of the cylinder and is pivotally connected to the upper end of an arm 20 carried by the upper portion of the said door 16. Surrounding the piston rod and bearing with its ends against the piston enrich.

and the end of the cylinder is a strong coil spring 21, said spring normally pressing the piston toward the other end of the cylinder, so as to swing and hold the door 16 in open position.

Mounted on the floor of the car, adjacent the pipe 15, is a valve casing 22, and disposed in this casing is a sliding valve23, said valve being formed with a vertical transverse passage 24 therethrough. Connected to the pipe 15 and to the upper side of the valve casing is a pipe 25, while a pipe 26 is connected to the lower side of the easing, directly opposite the pipe 25, and leads to or slightly weaker in force than the normal air; pressure in the pipe 15. Connected to the pipe 15, and entering the other end of the valve casing is a pipe 28, this pipe permitting the full pressure of the air of the train pipe to enter the valve casing, at all times, to drive the valve to the other end of the casing, against the tension of the spring. When the pressure in the train pipe is reduced, as when the brakes are applied to stop the train, the pressure of air through the pipe 28 from the train pipe 15, will be less than the force of the spring 27, which results in the spring pushing the valve into position to register its passage 24 with the pipes 25 and 26 and thus permit air to flow directly through the pipes 25 and 26 from the train pipe 15 to the'cylinder 17. This results in driving the piston to the other end of the cylinder and the closing of the door 16. The door will remain in closed position as long. as the brakes are set, but-as soon as the brakes are released and the normal air pressure is restored in the pipe 15 by the pumps of the brake system, the spring 27 will be overoome and the valve driven thereagainst and held with its pa'ssage out of registry with the pipes 25 and 26. In the outer end of the cylinder 17 there is formed a small bleed opening 21' from which the air is exhausted into the atmosphere, and whereby the spring 21 is permitted to move the piston into normal position to open the door 16.

Thus it will be seen that I have provided a novel and eflicient device for preventing refuse from the car toilets from being dropped on the tracks in stations or depots, thus obviating the necessity of the conductor ormovable by air pressure in the cylinder to brakeman locking and unlocking the toilet move the closure lnto operative position,
